BIO302: Human Anatomy

Unit 9: Digestive SystemDigestion allows you to extract useful nutrients from your food. The
digestive process begins as soon as you put food into your mouth, when
your teeth and saliva begin to break down food items into more
manageable sizes, and continues into the stomach and intestines. In
this unit we will familiarize ourselves with the names and functions of
each organ in the digestive system. We will also learn about the
structures of the unique tissues and glands that enable us to absorb
nutrients from food.

Unit9 Learning Outcomes
Upon successful completion of this unit, the student will be able to:
- Describe the functions of the digestive system and identify the
organs.
- Describe the anatomical structure of the mouth, esophagus, stomach,
small intestine, and large intestine.
- Describe the anatomical structure of the liver, gallbladder, and
pancreas.

Instructions: Please view the Lecture 32 (up to 41min into the
video) to learn about the anatomy of the mouth and esophagus, the
entryway into the digestive system.

Instructions: Please view the end of Lecture 32 (beginning 41min
into the video) and the beginning of Lecture 33 (until 4min into the
video) to learn about the anatomy of the stomach. As you watch,
please take note of the general anatomy, innervation of the stomach,
and digestive secretions, as listed in the subtopics below.

Instructions: Please read this page to learn about the anatomy of
the stomach. As you read, pay particular attention to understanding
the overall structure of the stomach, the means by which nerves
control it, and the digestive secretions that it produces, as listed
in the subtopics below.

Instructions: Please view Lecture 33 (beginning 4min into the
video) and the beginning of Lecture 34 (until 21min into the video)
to learn about the anatomy of the large and small intestines. As
you watch, please take note of the general anatomy, innervation of
the intestines, and digestive secretions, as listed in the subtopics
below.

Instructions: Please read both of these pages to learn about the
anatomy of the large and small intestines, where the majority of our
food is digested. As you read, pay particular attention to
understanding the overall anatomy of the intestines, the structures
of the cells and tissues that make them up, and the digestive
secretions they produce, as listed in the subtopics below.

Instructions: Please view the second half of Lecture 34 (starting
21min into the video) and the beginning of Lecture 35 (until 9min
40sec into the video) to learn about the contributions the liver,
gallbladder, and pancreas make to the digestive system. The anatomy
of each of these organs will be covered. As you watch, please pay
attention to both the gross (overall general) anatomy of each organ
and the anatomy of the cells and tissues in each organ, as listed in
the subtopics below.

Instructions: Please read this page to learn about the anatomy of
the liver and pancreas and their roles in the digestive system. As
you read, be sure to understand the overall structure of the liver
and pancreas in addition to the structure of the cells and tissues
that make them up.
